+  String.prototype.replaceAll ( searchValue, replaceValue )
+
+  10. Let position be ! StringIndexOf(string, searchString, 0).
+  11. Repeat, while position is not -1
+    a. Append position to the end of matchPositions.
+    b. Let position be ! StringIndexOf(string, searchString, position + advanceBy). 
+  ...
+  14. For each position in matchPositions, do
+    a. If functionalReplace is true, then
+      ...
+    b. Else,
+      ...
+      ii. Let captures be a new empty List.
+      iii. Let replacement be GetSubstitution(searchString, string, position, captures, undefined, replaceValue).
+
+  StringIndexOf ( string, searchValue, fromIndex )
+
+  ...
+  4. Let len be the length of string.
+  5. If searchValue is the empty string, and fromIndex <= len, return fromIndex.
+  6. Let searchLen be the length of searchValue.
+  7. If there exists any integer k such that fromIndex ≤ k ≤ len - searchLen and for all nonnegative integers j less than searchLen, the code unit at index k + j within string is the same as the code unit at index j within searchValue, let pos be the smallest (closest to -∞) such integer. Otherwise, let pos be -1.
+  8. Return pos. 
+
+  Runtime Semantics: GetSubstitution ( matched, str, position, captures, namedCaptures, replacement )
+
+  ...
+  2. Let matchLength be the number of code units in matched.
+  ...
+  4. Let stringLength be the number of code units in str.
+  ...
+  9. Let tailPos be position + matchLength.
+  10. Let m be the number of elements in captures.
+  11. Let result be the String value derived from replacement by copying code unit elements from replacement to result while performing replacements as specified in Table 53. These $ replacements are done left-to-right, and, once such a replacement is performed, the new replacement text is not subject to further replacements.
+  12 Return result.

+  Table 53: Replacement Text Symbol Substitutions

+
+  The nnth element of captures, where nn is a two-digit decimal number in the range 01 to 99. If nn ≤ m and the nnth element of captures is undefined, use the empty String instead. If nn is 00 or nn > m, no replacement is done.
